This study aimed to examine the effect of four different industrial starter cultures containing lactic acid bacteria (LAB) and bifidobacteria on selected characteristics of beverages prepared from buckwheat and stored at 4 °C for 28 days. This study included the determination of pH during fermentation and during refrigerated storage, determination of the number of LAB and bifidobacteria, and chromatographic analysis of carbohydrates. This study showed that the tested starter cultures effectively fermented the buckwheat beverage. There was a sufficient number of viable cells in the starter microflora for the obtained beverages to exhibit potential health-promoting properties. Beverages had stable pH values during refrigerated storage. The stored beverages showed changes in the content of selected carbohydrates, which indicates the constant biochemical activity of the present starter microflora. This study provides useful references on the metabolism of LAB in plant-based beverages.
本研究旨在考察四种含有乳酸菌(LAB)和双歧杆菌的不同工业发酵剂对用荞麦制备并在4℃下储存28天的饮料的选定特性的影响。本研究包括测定发酵过程中和冷藏储存期间的pH值、LAB和双歧杆菌的数量,以及碳水化合物的色谱分析。本研究表明,所测试的发酵剂有效地发酵了荞麦饮料。发酵剂微生物群落中有足够数量的活细胞,使得所获得的饮料具有潜在的促进健康特性。饮料在冷藏储存期间pH值稳定。储存的饮料中选定碳水化合物的含量发生了变化,这表明当前发酵剂微生物群落具有持续的生化活性。本研究为植物基饮料中LAB的代谢提供了有用的参考。
